Overview of Inter-Display Protocol Standardization with Wayland/Weston
This overview delves into the standardization of the Inter-Display Protocol using Wayland/Weston, focusing on sharing surfaces between ECUs and OSs. It explores the definition of the protocol at Wayland, receiver daemon, HMI transmitter plugin, Weston core, backend, adaptation plugins, and implementation of reference protocols like RTP, LVDS, and Ethernet AVB.

Use Case and Requirement Instrument cluster ECU Multimedia ECU The cockpit system consists of Multiple ECUs.
Use Case and Requirement Instrument cluster ECU There is use case and requirement to display surface to several display inter ECUs. Multimedia ECU Display map Display inter section enlarge view
Use Case and Requirement Instrument cluster ECU There is use case and requirement to display surface to several display inter ECUs. Multimedia ECU Telematics information Traffic Jam information
Use case and Requirement https://wiki.automotivelinux.org/eg-ui- graphics-req-graphics There will be more Use cases for Inter Display protocol as more useful navigation/telematics data come, connecting internet.
Standardization: which part? Instrument cluster ECU Multimedia ECU Telematics information Traffic Jam information
Inter Display protocol Standardization Instrument cluster ECU Multimedia ECU Telematics information Traffic Jam information Standard Protocol at Wayland/Weston
Overview: Inter Display protocol with Wayland/Weston Now way to share surface inter ECUs/OSs . HMI HMI Transmitter Plugin ivi-shell ivi-shell Controller Controller Weston Core Weston Core Weston Backend Weston Backend Input devices Input devices
Overview: Inter Display protocol with Wayland/Weston Define Protocol at Wayland protocol to be upstreamed Receiver Daemon HMI Transmitter Plugin HMI Transmitter Plugin ivi-shell ivi-shell Controller Controller Weston Core Weston Core Weston Backend Weston Backend Adaptation Plugins Adaptation Plugins Input devices Input devices Implementation of reference protocol - RTP - LVDS - Ethernet AVB,,,
Summary Inter Display protocol is really mandatory for near feature to collaborate with ECUs. Wayland/Weston community is the best place to be upstreamed. Define Inter Display protocol Reference implementation to share physical memory needs to be adapted for each users preferable. At first, Linux <-> Linux environment. To be proposed to SAT as AGL activity. TODO: collaboration with Security framework.
